+# 面板服务端
+
+- 基于Koa
+
+## docker
+
+<!-- 修改版本号 -->
+- 构建镜像：docker build -t chaoszhu/easynode:v1.1 .
+- 推送镜像：docker push chaoszhu/easynode:v1.1
+
+> `docker run -d --net=host easynode-server`
+<!-- > `docker run -d -p 8888:8082 -p 22022:22022 easynode-server` -->
+
+## 遇到的问题
+
+> MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 input listeners added to [Socket]. Use emitter.setMaxListeners() to increase limit
+- ssh连接数过多(默认最多11个)
+- 每次连接新建一个vps实例，断开则销毁
+
+> Error signing data with key: error:0D07209B:asn1 encoding routines:ASN1_get_object:too long
+- 经比对，ssh的rsa密钥在前端往后端的存储过程中丢失了部分字符
+
+> 获取客户端信息：跨域请求客户端系统信息，建立ws socket实时更新网络
+- 问题：服务端前端套上https后，前端无法请求客户端(http)的信息, 也无法建立ws socket连接(原因是https下无法建立http/ws协议请求)
+- 方案1: 所有客户端与服务端通信，再全部由服务端与前端通信(考虑：服务端/客户端性能问题). Node实现http+https||nginx转发实现https
+- 方案2: 给所有客户端加上https(客户端只有ip，没法给个人ip签订证书)
+
+## 构建运行包
+
+### 坑
+
+> log4js: 该module使用到了fs.mkdir()等读写api，pkg打包后的环境不支持，设置保存日志的目录需使用process.cwd()】
+
+> win闪退: 在linux机器上构建可查看输出日志
+
+## 客户端
+
+> **构建客户端服务, 后台运行** `nohup ./easynode-server &`
+
+> 功能：服务器基本信息【ssh信息保存在主服务器】
